Best Answer

Multiply the numerator and the denominator of one fraction by the same denominator and, if you need to, do multiply the second fraction's numerator and denominator by the same number so they will have like denominators. Then subtract. For example:

1/2 - 1/3

1/2 x 3/3 = 3/6

1/3 x 2/2 = 2/6

3/6 - 2/6 = 1/6 -----> ANSWER
